This calculation does not account for advancements in technology. I guess you have seen those ads from the 90's showing high performance computers costing $10k.

This calculation does not account for advancements in technology. I guess you have seen those ads from the 90's showing high performance computers costing $10k. Well, current computers have several orders of magnitude higher performance, yet we are not expecting the prices to be in the millions. Instead, we expect the technology to advance on its own pace while the prices keep up with inflation. The problem here is that Nvidia is effectively a monopoly in high-performance GPU segment so the prices are out of hand and supply doesn't match demand.
